Gas Pumps

all my life i have always used just the hand powered pumps to blow up my bike tires, but now i would like something easier and less effort to use. i have heard about these pumps that use gas. What i would like to know is:
How much do these cost?
How big are they? (can i fit them in my bag?)
How many tires can one gas canester fill?
How much does the gas cost? or can you get it refilled at LBS?
Or can anybody recomend other pumps that i can carry with me but are easy to use.
By the way i live in UK so can you put proices in GBP.
Cheers
Aidan

Pumping up a tire is to hard? You must be one heck of a bike rider.

I think you are referring to CO2. It is mainly just used out on the trail when you get a flat. You should still use your regular floor pump for your pre-ride tire top offs.

As for how much. The inflator is generally around $10 - $15 US. Then you will need to buy extra CO2 cartridges. I just buy a box of 25 at Wal-Mart for about $15 or something like that. I bought a box about two years ago and I still have about 5 left.

I was just kidding.

One cartridge will pump up a road tire but it will be a little small to get a large MTB tire to pressure. You can buy bigger volume cartridges for MTB tires but they are expensive. Make sure you get a pump that will take UNTHREADED cartridges.

Make sure if you buy one of the inflators you get one that is NOT threaded so you can use the cheap CO2 cartridges that LowCel is talking about. This is the one I have - http://www.rei.com/online/store/Prod...ory_rn=4500856

Thanks for pointing out the non-threaded part. I didn't even think about that part of it. I have basicly the same inflator you do, just a couple of years older and not nearly as pretty.

I bought a SuperFlate waaaay back in '97 or '98. Haven't used it once (I simply don't get flats...) It used CO2 cartridges (cheap), and takes 2 to inflate a MtnBike tire. My SuperFlate actually rusted around the valve stem connector due to my sweat dripping down onto the waist pack I carried it in. I haven't even carried a pump in about 7 years.... I imagine they'd be great for racing events, where you need to inflate very quickly.

I got some cartridges there recently and was surprised that 15 were only $3. hoo hoo for paintball guns!

They're pretty small so yes you could fit them in most under seat bags

Non-refillable. Generates a lot of waste (recyclable, but still)

Modern hand pumps are simple to use. I prefer Crank Bros or Topeak

Actually they ARE refillable. You just need one badass compressor to do the job.

I have a friend who knows the people at the paintball shop. The compressors they use to refill the gun cartridges will also do bike CO2 cartridges.

For the original poster, the main point of the CO2 cartridges is a FAST refill. The target audience is racers (lazy people are the secondary audience).

If you are worried about refilling on trail after a flat, you may want to buy one of those "Seal n' flate" things with the latex. This will get you going again about as fast as anything.

Which few people have access to. Which brings me back to my original point on the matter
